I'm planning on purchasing a k3 tomorrow and was curious about mounting Leica M lenses on it via a Leica M - M42 adaptor, since I already own an M mount lens for another camera. I know M lenses generally don't work on systems with a mirror because they're built for rangefinders, but I've found an adaptor online that claims focus-to-infinity as a feature (without a lens element in the adapter).
I'm skeptical but frankly don't know enough about lens adapting to go through with the purchase without further research. Has anyone tried to mount an M lens of a K-3?
Thanks for the help!
